8 valence electrons are needed for an element to become stable, which is why the noble gases do not interact with any other elements. They are already stable. However, the exception is Helium, the first noble gas, which only has two valence electrons. 8 valence electrons are needed on the 2nd and 3rd valence shells for any molecule to become stable.
What else can I help you with?
Will silicon lose or gain electrons?
Silicon will tend to gain electrons in order to achieve a stable outer electron configuration, as it has 4 valence electrons and typically forms covalent bonds with other elements by sharing electrons.
How can you tell if an element will conduct energy?
Elements are in fact a bundle of energy if you will. I believe what your asking is How can you tell if an element will conduct electricity. If an atom contains less the the required atoms for its outer shell to become full and stable, it is classified as a conductor. Here's why: The atoms of a given element is composed of the protons, neutrons, and electrons. Electrons are the "electricity" part of an atom. These electrons orbit the protons and neutrons that are at the center of the atom. The electrons are in Valence shells, which is basically which orbit the electrons are on, the closest shell/orbit can contain only 2 electrons, and then it is said to be stable and full; the second valence shell/orbit can only contain 8 electrons, and then it is said to be stable and full; the third valence shell/orbit can only contain 8 electrons, and then it is said to be stable and full also ect.... Now, if we took the third valence shell, and it only contained 1 electron, it is NOT stable and full, so this 1 electron/electricity-part-of-the-atom is free to float around to other empty shells. This is due to the fact that the electrons always want to be in a stable shell/orbit. Some atoms of certain elements naturally contain a full AND therefore stable outer valence shell, (the furthest shell/orbit away.) If an atom contains less the the required atoms for its outer shell to become full and stable, it is classified as a conductor.
What electrons are involved bonding?
Valence Electrons!
What are electrons in the outer shell called?
Electrons in the outermost energy level of an atom are called valence electrons. These electrons are involved in forming chemical bonds with other atoms to achieve a stable configuration. The number of valence electrons determines an element's reactivity and chemical properties.
Do the elements in the oxygen family tend to gain or lose electrons in chemical reactions?
Elements in the oxygen family tend to gain electrons in chemical reactions. This is because these elements, like oxygen, have six valence electrons and typically achieve a stable electron configuration by gaining two electrons to complete an octet.
What is the purpose of elements to lose or gain valence electrons to become an ion?
Elements lose or gain valence electrons to become ions in order to attain a stable electronic configuration, usually by achieving a full outer electron shell. This helps them to increase their stability and decrease their overall energy. Ions can either become positively charged (cation) by losing electrons or negatively charged (anion) by gaining electrons.
What is the number of electrons needed for stability in the groups of the periodic table?
They r noble gases which have stable valance shell and grotp no. 18
How many valence elactrons do all the elements in neon's family have?
8 valence electrons are there in in neon's family .They are stable in nature.
How does a atom become stable?
When the atom has 8 valence electrons.
All atoms become stable when they have how many valence electrons?
Atoms become stable when they have a full outer electron shell, which typically means having 8 valence electrons (except for hydrogen and helium, which are stable with 2 valence electrons). This stable configuration is known as the octet rule.
How many electrons to most elements need to become stable?
Most elements need 8 electrons in their valence shells.
How many valence electron level does an element have?
Except for elements 1 and 2, all elements are stable with how many electrons in their outermost (valence) level?
How many valance electrons does nitrogen?
5 valence electrons because it needs to gain 3 electrons in order to become stable
The tendency of an element to react chemically is closely related to what?
its Atomic Mass.
How is an elements most likely state related to its valence electrons?
An element's most likely state is related to its valence electrons because valence electrons determine an element's reactivity and ability to form chemical bonds. Elements with a full valence shell are stable and often found in a solid state, while elements with incomplete valence shells are more reactive and tend to form compounds in order to achieve a stable electron configuration.
Elements that have one valence electron tend to?
Elements that have one valence electron tend to be highly reactive and readily form positive ions by losing that electron to achieve a stable electron configuration. These elements include alkali metals like lithium, sodium, and potassium.
How many valence electrons does calcium lose?
Calcium loses 2 valence electron to become ionized.
